Hyannis, intheflcounty of Grant and ifyl l z ait known. that I, HENRY cltlzen of the United States, residing t LARUE, a t ate of Nebraska, have invented certain new and useful Improvements in Threshing-Cylinders, of whichthe following is a specification, reference being hadto the accompanying drawings.

lhis invention relates to an improved 'threshingcylinder, and has for its primary object to provide a cylinder for'threshing machines and the like having certain novel structural features, whereby any. one or more of the teeth may be readily removed when broken and replaced by new teeth.

' A further and more specific object of theinvention resides in the provision of a threshing cylinder embodying in its construction a plurality of disks, the opposed faces of adjacent disks being provided with teeth receiving recesses, and means for rigidly connecting the cylinder disks and preventing their relative longitudinalmovement upon the driving shaft.

The invention has for a further object to provide a device of the above character which is simple and durable in its construction, may be produced at small manufacturing cost,and is highly efficient, reliable and convenientin practical use.

'lVith the above and other objects in view, which will become apparent as the descriptionproceeds, the invention consists incertain details of construction, combination and arrangement of parts as will be more fully hereinafter described and claimed.

For a full understanding of the invention, reference is to be had'to the following description and accompanying drawlngs, in

Figure 1 is a side elevation of a threshing cylinder constructed in accordance with the preferred embodiment of my invention. Fig. 2 is a section taken on the line 2-2 of Fig. 1. Fig. 3 is a section taken on the line 33 of Fig. 2. H

Referring-fin detail to the drawings, 5

cesses 8;which.;open at their outer ends upon thegfperiphery of the; disk. The recesses in one face of the disk are staggered ordisposed intermediate of the recesses in the opposite face of the diski .The recesses he p Patented Sept, 22,1914. 'Applicationfiled March 7,1914, Serial No. 823,158. a i

in the face of one-[disk are adapted to receive portions of'the cylinder teeth 9 which are d1s posed in; the recesses" in the opposed face of an ad acent disk,.said cylinder teeth beingrigidlylsecured to the latter disk by means of bolts or rivets shown at 10, the

nut ends of which are countersunk as at 11 in the opposite face of the disk. It will thus be apparent that when the disks 5 are assembled to form the threshing cylinder, the teeth 9 will be arranged in staggered relation as clearly shown in Fig. 1 of the drawing. These disks are provided with a circularly arranged series of openings 12 between the central openings 6 and the teeth receiving recesses, said openings coinciding or registering with each other when the disks are assembled to receive the con necting or tie rods 13. lhese rods are provided with heads upon one of their ends and nuts 14 are threaded upon the opposite ends thereof for engagement with one end of .the cylinder to draw the rods through the cylinder disks and tightly clamp said disks together upon the cylinder shaft.

From the foregoing description taken in connection with the accompanying drawing, it is believed that the construction, manner of operation and several advantages of my invention will be clearly and fully understood.-' It will be observed that by constructing the cylinder of a plurality of disks the threshing teeth may be very easily and quickly removed when necessary. S6V- cylinder disks upon a rectangular cylinder shaft, they may be readily secured upon a. cylindrical shaft in any approved manner. Owing to the extremely simple construction of the invention it will further be appreciated that the same can be produced at small manufacturing cost.

Wl/ hile I have shown and described the preferred enibodiinent of my invention,

"therefore reserve the privilege ofresorting to all such legitimate changes as may be fairly embodied Within the spirit and scope of the invention as claimed.

.VVhat is claimed is: The herein described threshing cylinder including aplurality of disks, each of said disks being provided in its opposite faces with recesses opening upon the periphery thereof, the recesses in one face of the disk being arranged in staggered relation to the recesses in the opposite face thereof, threshing teeth adaptedto be arranged in the recesses in one face of each disk and to Copies of this patent may be' obtained for posed through sai openings to connect the .disksand hold the same against relative movements I Iii-testimony whereof I hereunto afiix my signature in the presence of tWo Witnesses. HENRY' A RUE.
